[0002] PET board is mainly made of polyester raw materials extruded by extruder at high temperature, and extruded through different diameter molds to obtain boards of different thicknesses. The main ingredients include polyethylene terephthalate PET and polybutylene terephthalate PBT resin. Polyethylene terephthalate is also commonly known as polyester resin, commonly known as polyester resin. It is a condensation product of terephthalic acid and ethylene glycol, and together with PBT, it is collectively called thermoplastic polyester, or saturated polyester. PET and PBT together as thermoplastic polyesters have become one of the five major engineering plastics.
